Jayne Gackenbach of Grant MacEwan University in Canada says about 100 members of the military were surveyed about their gaming habits.

"Low gaming" respondents, those who didn't play much, or played more casual games, showed signs of having more combat-related nightmares.

Gackenbach, who spoke at the Game Developers Conference last week, thinks that video games serve as a "threat simulator" that conditions the mind to cope with intense situations when they come up in nightmares.

One soldier wrote to Gackenbach, saying, "I would see many soldiers, in combat, with PSPs or anything we could hook up to 220v electricity. When soldiers weren't on patrol, we often had violent war games on our systems. It was weird. Like we didn't get enough violence."
